BACKGROUND OF THE INVENTION

The invention concerns an operating device for a loading crane, and aloading crane having such an operating device.

An operating device of the general kind set forth has long been used inloading cranes.

What is problematical in that respect is that loading cranes have ahighly dynamic field of use, which makes it difficult to plan operationsthereof. Therefore safety-relevant decisions have to be made by the userof the crane during operation thereof on site. Frequently the workingarea can be difficult to oversee, and the result of this is that theuser has to change his position. The user often has to turn his viewaway from the load to be craned in order to look at the operatingdevice. Often the user is uncertain about the currently prevailingoperating parameters of the crane. If the user is to have a clearpicture about the currently prevailing operating parameters of the cranethe question which also arises is how they can be processed andcommunicated to the user.

SUMMARY OF THE INVENTION

The object of the invention is to provide an operating device of thegeneral kind set forth and a loading crane, in which the above-discussedproblems are avoided.

Like an operating device of the general kind set forth for a loadingcrane, the operating device which is used in relation to the presentinvention also has a crane controller for controlling actuators of theloading crane and an input device for the input of control commands forthe crane controller. In that case the actuators of the loading craneare controlled by the crane controller based on the input controlcommands. In addition the crane controller is adapted to evaluate sensorsignals from sensors of the loading crane and to generate sensor data onthe basis of the sensor signals. Furthermore the input device isspatially separate from the crane controller, as is the case for examplewith a radio remote control.

The crane controller has a first telecommunication device for theexchange of data signals with the input device, the data signalsdelivered by the crane controller including sensor data. Similarlythereto, the input device has a second telecommunication device for theexchange of data signals with the first telecommunication device, thedata signals delivered by the input device including control commands.Therefore (inter alia) data signals in the form of sensor data andcontrol commands can be exchanged by the crane controller and the inputdevice.

According to the invention, the operating device has a signaling devicewhich is spatially separate from the input device and which can be wornby a user on the body. In that respect, the input device has atransmitting device for the delivery of data signals which can bereceived by a receiving device of the signaling device. It is furtherprovided that the signaling device, which can be worn by a user on thebody, has a displaying device, by which audio and/or image data can bedisplayed, wherein the signaling device signals the audio data and/orimage data to a user.

The represented audio data and/or image data may include informationabout the currently prevailing operating parameters of the loading craneand optionally the operating device itself, information about a workingprocess or lifting process of the loading crane, which is planned, whichis currently being performed or which is to be performed, informationabout the surroundings of the crane and/or the user or information forthe support of repair and/or maintenance operations on the loadingcrane. The working stress for a user can be reduced and the operatingsafety of a loading crane can be enhanced by the representation of audiodata and/or image data.

The audio data and/or image data are basically (but not necessarilyexclusively) produced on the basis of the sensor data, wherein there areprovided three variants for the generation thereof:

In a first variant, the data signals delivered by the crane controllerto the input device include sensor data and the input device deliversthose data to the signaling device by means of the transmitting device.The signaling device has a processor which now generates the audio dataand/or image data on the basis of those sensor data.

In a second variant, the input device has a processor which generatesthe audio data and/or image data on the basis of the sensor datadelivered by the crane controller to the input device. The audio dataand/or image data are now output by means of the transmitting device tothe signaling device.

In a third variant, the controller has a processor which generates audiodata and/or image data on the basis of the sensor data, and outputs sameto the input device by means of the first and second telecommunicationdevices and the input device delivers the audio data and/or image datato the signaling device by means of the transmitting device.

Therefore, the three variants substantially differ as to where the audiodata and/or image data which are signaled to a user by the signalingdevice are generated on the basis of the sensor data.

The crane controller is adapted to control actuators of the loadingcrane. Control of the actuators is effected on the basis of controlcommands, wherein the control can include for example switching valves(like for example a directional control valve), hydraulic devices orsupplying power to electrical devices.

The actuators can generally involve electric or hydraulic drives of aloading crane or mobile crane like for example hydraulic cylinders,electric or hydraulic drives of winches, electric or hydraulic drives ofslewing drives or electric or hydraulic drives for or of working devicesor attachments.

Control commands for the crane controller can be input by the inputdevice which is spatially separate from the crane controller. Input ofthe control commands can be effected for example by a user by way of akeypad, operating knobs, operating levers or the like. In that respecthowever the possibility should not be excluded that control commands forthe crane controller can also be input by other units of the operatingdevice. The input device can be arranged for example in a mobileoperating console like for example a radio remote control, or in anoperating station. The mobile operating console which can be portableand the operating station which can be arranged on the loading craneand/or on a vehicle having a loading crane can communicate wirelessly orwired with the crane controller. The input device can therefore be inthe form of a mobile controller or a mobile control module. The inputdevice can be interpreted as (at least one) part of a stand-alone(possibly portable) operating unit, with which a user can movesubstantially freely in a certain area around a loading crane or ahydraulic lifting apparatus.

The sensors of the loading crane can be sensors for detecting the stateof the loading crane and the state of attachments and the area aroundthe loading crane. Examples of such sensors are for instance pressuresensors, rotary encoders, angle sensors, force measuring cells, opticalsensors, ultrasound sensors, proximity sensors, acoustic sensors,temperature sensors or acceleration sensors. Sensor signals canrespectively emanate from those sensors like for example analog and/ordigital electrical signals. The crane controller is adapted to generatecorresponding sensor data from the sensor signals fed to the cranecontroller for example by way of wired or wireless signal connections.Thus for example sensor data corresponding to a measured pressure can begenerated by the crane controller from an electric voltage output by apressure sensor. In generation of the sensor data for example thegeometry, equipment and operating state of the loading crane can beincorporated.

Data signals which are exchanged between the crane controller and theinput device can include sensor data and control commands.

Data signals exchanged between the input device and the signaling devicecan include sensor data, however it should not be excluded that thosedata signals also include control commands.

A user can be a person who is operating the loading crane by means ofcontrol commands. In that respect it can be provided that the loadingcrane is also operated by a plurality of users.

The signaling device is designed so that it can be worn by a user on thebody, that is to say the at least one part of the signaling device canbe arranged on or at a part of the body of a user. Such a signalingdevice can be in the form of data goggles, a smartwatch, a smartphone, atablet, a headset, ear buds and the like.

Furthermore, the signaling device has a displaying device, by means ofwhich audio data and/or image data can be displayed to a user. Imagedata can be reproduced by the displaying device in such a way that theycan be optically perceived by a user. A displaying device for imagedata, that is to say an optical display, can be for example in the formof an optical display like for example an at least partially opaque,semi transparent or transparent display. Audio data can be reproduced bya displaying device for audio data in such a way that they can beperceived acoustically by a user. A displaying device for audio data,that is to say an acoustic display, can be for example in the form of asound transducer like for example a loudspeaker or a bone conductionheadphone. The audio data and/or image data can basically include statusinformation about the operating state of the loading crane, informationrelating to the area around the loading crane and the user as well asacoustic and/or optical warning alerts.

The signaling device can superimpose the image data at least on a partof a visual field of the user or fill at least a part of a visual fieldof the user with the image data. The audio data and/or image data can bedisplayed to the user without the user having to turn his view away fromwhat is actually happening at the time, that is to say for example aworking operation or lifting operation which is currently beingperformed. Audio data and/or image data of regions which are outside thevisual field of the user can also be represented to the user.

In that respect, it may be advantageous that the signaling devicesuperimposes the visualized image data only on a part of the visualfield of the user or fills only a part of the visual field of the userwith the image data. The image data are therefore not superimposed onthe entire visual field of the user or it is not the entire visual fieldof the user that is filled with image data. With a suitably designedsignaling device therefore the user always sees a real image on which avirtual image is superimposed. In the case of lags in the representationor even a failure of the superimposed or inserted image (virtual image)the user always still has what is actually happening (the real image) inhis field of view.

The processor or a processor of the crane controller, the input deviceor the signaling device is adapted to produce audio data and/or imagedata on the basis of the sensor data. The processor can be in the formof an autonomous component or a data-processing logic unit (for examplea processor core).

The first and second telecommunication devices can be in the form ofwireless telecommunication devices, preferably short-wavetelecommunication devices, particularly preferably ISM telecommunicationdevices, wifi telecommunication devices or Bluetooth® telecommunicationdevices. Generally the transmitting device and the receiving device canbe in the form of wireless communication devices or wiredtelecommunication devices.

It can be advantageous for sensor data and control commands to becommunicated by way of different communication channels or by way of thesame communication channel. It can therefore be provided that thecommunication of given data signals is effected by way of a dedicatedparallel second transmission channel. In that way for example thetransmission of control commands and the transmission of other datasignals can be effected separately from each other. Thus it is alsopossible to use different communication standards. Thus it can bepossible for safety-relevant data signals like for example a controlcommand to use certified hardware with for example suitable encryption,frequency spread or plausibility control while for the transmission ofother data signals it is possible to use a simpler and possibly alsofaster connection like for example an ISM radio connection.

It can be advantageous in that respect for the communication channel orchannels to be encrypted. In that way eavesdropping on or influencing ofthe transmission of data signals can be prevented or made difficult. Thedemands on encryption can in that case distinguish different datasignals.

It can be advantageous if the transmitting device of the input device isformed by the second telecommunication device.

It can generally be advantageous if the input device has a power storagemeans for the power supply for the signaling device. The power supplywhich can also include charging up a power storage device of thesignaling device can be effected in that case in wired or wirelessfashion (for example inductively).

The crane controller for generating the sensor data from the sensorsignals is or can be connected to a cloud computing computer unit. Thus,for example, the sensor signals detected by the crane controller, whichcorrespond to the geometry, equipment and the operating state of theloading crane, can be communicated to a cloud service by way of asuitable telecommunication device. There, sensor data can be generatedfrom the communicated sensor signals by the cloud computing unit andsubsequently communicated to the crane controller.

It can be advantageous if the crane controller detects the position ofthe signaling device. Alternatively thereto or in combination therewithit can be provided that the signaling device detects a position of theuser and/or a part of the body of the user and/or a visual field of theuser (direction of view) relative to the loading crane. Detection of theor a position and/or the visual field can be effected for example byradio direction finding, a GPS system or by means of an opticaldetection device like for example a camera of the signaling device.

The detected position or positions or the detected visual field arecommunicated as data signals which can be generated for example by aprocessor to the input device by means of a communication device and theinput device outputs the communicated data signals to the cranecontroller by way of the second and first telecommunication device. Thecrane controller is adapted to implement control commands output by auser in dependence on the detected position of the signaling deviceand/or the user and/or the part of the body of the user and/or thevisual field of the user relative to the loading crane. Detection of theor a position and/or the visual field can be effected for example by wayof radio direction finding, a GPS system or by means of an opticaldetection device like for example a camera of the signaling device.

The output of control commands by a user or the implementation ofcontrol commands by the crane controller can therefore be permitted orprevented in dependence on the detected position of the signaling deviceand/or the user and/or the part of the body of the user and/or thevisual field of the user relative to the loading crane. It is alsopossible for control commands to be generated in dependence on thedetected position of the signaling device and/or the user and/or thepart of the body of the user and/or the visual field of the user. Thusfor example a so-called gesture control can be implemented for exampleby detection of the position or positions.

It is further possible for audio data and/or image data to be displayedin dependence on the detected position or positions.

As already mentioned in the opening part of this specificationprotection is also claimed for a loading crane having an operatingdevice as described hereinbefore.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an embodiment of a loading crane 14 with an operatingdevice in the form of a crane controller 1, an input device 2 and asignaling device 3. In the illustrated structure, the input device 2 isarranged at a mobile operating console 11 and the signaling device 3 isin the form of data goggles 37. To detect a visual field of thesignaling device 3 in the FIG. 1 embodiment, it has an optical detectiondevice 33 such as a camera.

The loading crane 14 can be mounted with its crane base 15 for exampleon a vehicle. A crane post 16 rotatable about a vertical axis is mountedon the crane base 15. A lift arm 17 which is pivotable about ahorizontal axis by means of an actuator in the form of a hydrauliccylinder 22 is arranged on the crane post 16. In turn arranged on thelift arm 17 is a crane arm extension 18 which is pivotable about ahorizontal axis by means of a further actuator in the form of ahydraulic cylinder 23, the extension 18 having at least one telescopicextension boom arm 19. As shown in the FIG. 1 embodiment an attachmentarm 20 can be arranged on the crane arm extension 18, the arm 20 alsobeing pivotable by means of a further actuator in the form of ahydraulic cylinder 24 about a horizontal axis. Equally, the attachmentarm 20 can have at least one telescopic extension boom arm 21. Foradditional support for the loading crane 14 or a vehicle carrying theloading crane 14 there is provided a support arrangement withoutriggers, of which one outrigger 25 is shown in the FIG. 1 view andwhich can have extendable telescopic support legs. In addition a workingunit 36 in the form of a winch is arranged on the attachment arm 20 ofthe loading crane 14.

Besides the above-mentioned components, the loading crane 14 has varioussensors for detecting the instantaneous position or geometry of theloading crane 14. For the outriggers 25, there are switches S3, S4 fordetecting the supporting state of the outrigger on the ground. It isalso conceivable that the extended position of the outrigger 25 isdetected by a travel measuring device (not shown here). A rotary encoderDG1 is provided for detecting the rotary angle of the crane post 16relative to the crane base 15. A further rotary encoder DG2 is providedfor detecting the bend angle in a vertical plane between the crane post16 and the lift arm 17. The hydraulic pressure in the hydraulic cylinder22 of the lift arm 17, which pressure is characteristic of the cranecapacity, involves a pressure sensor DS1. A rotary encoder DG3 isprovided for detecting the bend angle between the lift arm 17 and thecrane arm extension 18 in a vertical plane. A pressure sensor DS2 isprovided for detecting the hydraulic pressure in the hydraulic cylinder23 of the crane arm extension 18. A switch S1 is provided for detectingthe retraction state of an extension boom arm 19 of the crane armextension 18. A rotary encoder DG4 is further provided for detecting thebend angle between the crane arm extension 18 and the attachment arm 20in a vertical plane. A pressure sensor DS3 is provided for detecting thehydraulic pressure of the hydraulic cylinder 24 of the attachment arm20. A switch S2 is provided for detecting the retraction state of anextension boom arm 21 of the attachment arm 20. In principle, it shouldnot be excluded that the extension position of the individual extensionboom arms is detected by an extension position sensor with, for example,a travel measuring device.

The sensor signals are respectively fed to the crane controller 1 bysignal inputs, of which by way of example the signal inputs 6, 7 for thesensor signals of the pressure sensors DS1, DS2 are shown. Sensor dataare then computed in the crane controller 1 from those sensor signalsand from data stored in a memory 10 and in this example specific to theloading crane 14, by a processor P of the crane controller 1, the sensordata being characteristic of the currently prevailing lift loadsituation or the operating state of the loading crane 14. The dataspecific to the loading crane 14 can be, for example, informationrelating to equipment, functions and limit values of operatingparameters of the loading crane 14 and any working units. Thus, forexample, sensor data which correspond to a measured pressure in thecorresponding hydraulic cylinders 22, 23 can be calculated from theelectrical voltages or signals output by the pressure sensors DS1, DS2.The crane controller 1 can also be connected to a cloud computingcomputer unit for generation of the sensor data from the sensor signals.Thus, for example, the sensor signals detected by the crane controller 1can be communicated to a cloud service by a suitable telecommunicationdevice. There sensor data can be generated from the communicated sensorsignals by the cloud computing computer unit and subsequentlycommunicated to the crane controller 1. It can also be possible totransmit specific data for the loading crane 14 to a cloud service or toretrieve same from a cloud service.

The crane controller 1 is adapted to control the actuators of theloading crane 14. Control commands for the crane controller can bedelivered by the input device 2. The input device 2 can be spatiallyseparate from the crane controller 1 and in the illustrated embodimentis arranged in a mobile operating console 11.

As can also be seen from a comparison with FIGS. 2 a, 2 b and 2 c whichrespectively show diagrammatically different configurations of theoperating device the crane controller 1 in each case has a firsttelecommunication device 4 for the exchange of data signals with theinput device 2 and the operating console 11, wherein the data signalsdelivered by the crane controller 1 include the sensor data. Similarlythereto, the input device 2 has a respective second telecommunicationdevice 5 for the exchange of data signals with the firsttelecommunication device 4, and the data signals supplied by the inputdevice 2 include control commands.

The operating device further has a respective signaling device 3 whichcan be worn by a user (41) on the body. It is provided that the inputdevice 2 has a respective transmitting device 6 for outputting datasignals, wherein the data signals can be received by a receiving device7 of the signaling device 3. It is further provided that the signalingdevice 3 which can be worn by a user (41) on the body has a displayingdevice 9, by which a user (41) can be displayed audio data and/or imagedata. The displaying device 9 in that case can include an opticaldisplay 33 as discussed hereinbefore as well as an acoustic display 34as discussed hereinbefore. The signaling device 3 can generally have aprocessor which for example is adapted to control the displaying device9 corresponding to the signaling or reproduction of the audio dataand/or image data. The operating console 11 can also have a display 12(and a processor suitably adapted for the display), which for examplecan serve for the display of data signals like for example sensorsignals. It can be provided that the transmitting device 6 of the inputdevice 2 is formed by the second telecommunication device 5.

The input device 2 and the signaling device 3 can respectively have apower storage element 38, 39. The power supply of the signaling device 3can however also be implemented by the input device 2, like for examplethe power storage element 38 thereof and a suitable connection.

The signaling device 3 can have a communication device 8, by which adetected position or a detected visual field of the signaling device 3can be communicated to the input device 2 as data signals which forexample can be generated by a processor of the signaling device 3.

FIG. 2 a shows a first configuration of the operating device. In thisconfiguration, data signals which include sensor data are delivered bythe crane controller 1 to the input device 2 by a wireless connection 26and/or a wired cable connection 27 supported by the firsttelecommunication device 4 and the second telecommunication device 5.The input device 2 passes those sensor data to the signaling device 3 bya wireless connection 28 and/or a wired cable connection 29 supported bythe transmitting device 6 and the receiving device 7. In thisembodiment, the signaling device 3 has a processor P3 which now on thebasis of those sensor data generates the audio data and/or image datawhich are to be signaled to a user (41). It will be appreciated that astorage element 30 for the storage of computed and/or received data canbe provided for the signaling device 3.

FIG. 2 b shows a second configuration of the operating device. In thisconfiguration, the input device 2 has a processor P2 which on the basisof the sensor data delivered by the crane controller 1 to the inputdevice 2 generates the audio data and/or image data which are to bedisplayed to a user (41). It is accordingly provided that the audio dataand/or image data are delivered by the transmitting device 6 to thereceiving device 7 of the signaling device 3. It will be appreciatedthat a storage element 31 for the storage of computer and/or receiveddata can be provided for the input device 2.

FIG. 2 c shows a third configuration of the operating device. In thisconfiguration, the crane controller 1 has a processor P3 which producesaudio data and/or image data on the basis of the sensor data anddelivers same to the input device 2 by the first and secondtelecommunication devices 4, 5. The input device 2, by the transmittingdevice 6, delivers the audio data and/or image data to the signalingdevice 3.

As can be seen from the configuration of the crane controller 1 in FIG.1 , the configuration of the operating device shown in FIG. 1 cancorrespond to that of FIG. 2 a or FIG. 2 b . With the provision of aprocessor P3 (and optionally a storage element 32) the configuration ofthe operating device shown in FIG. 1 however can also be of a designcorresponding to the configuration shown in FIG. 2 c.

Generally, it should not be excluded that the processors P1, P2, P3 forgenerating the audio data and/or image data are in the form of anindependent processor or an independent component or a data-processinglogic unit (for example a processor core) of an existing processor.Similarly, thereto the storage elements 30, 31, 32 can be independent orin the form of part of existing storage elements.

FIG. 3 shows a vehicle 40 having a loading crane 14 and an embodiment asshown for example in FIG. 1 of the operating device with an input device2 and a signaling device 3.

FIG. 4 shows a further embodiment of a vehicle 40 having a loading crane14 and a configuration as show for example in FIG. 1 of the operatingdevice with an input device 2 and a signaling device 3 which is carriedby a user 41, in the form of a further configuration of data goggles 37.The operating device can be so designed that the position of thesignaling device 3 is detected by the crane controller 1. In theillustrated embodiment therefore the position of the signaling device 3can be detected in the coordinate system x,y,z of the vehicle 40 or theloading crane 14.

In addition, the signaling device 3 can detect a position of the user41. In the illustrated embodiment, it is also possible to determine theorientation of the coordinate system u,v,w of the signaling device 3relative to the coordinate system x,y,z of the vehicle 40 or the loadingcrane 14—and thus an orientation of the user 41 relative to the vehicle40 or the loading crane 14.

It is further possible to detect the position of a part of the body 42of the user 41 relative to the loading crane 14 or relative to thesignaling device 3. Furthermore, the visual field 43 of the user 41 canbe detected relative to the loading crane 14. Thus, for example it isalso possible to detect the position of a part of the body 42 of theuser 41 in the visual field 43 of the user 41. In that way, it is alsopossible for example to detect a sequence of movements of a part of thebody 42 of the user 41 (gestures). It that case, the visual field 43 ofthe user can be detected for example by way of an optical detectiondevice (see reference 35 in FIG. 3 ).

The detected positions can be communicated by the signaling device 3 asdata signals to the input device 2 by means of a communication device 8and the communicated data signals can be further delivered to the cranecontroller 1 by the input device 2 by way of the second and firsttelecommunication devices 5, 4. The crane controller 1 can now basicallybe adapted depending on the detected positions to generate controlcommands and/or carry them out. Thus, control commands of the user 41can be carried out depending on the detected position of the signalingdevice 3. Furthermore, control commands can be carried out depending onthe detected position of the user 41, and therefore can be carried outdepending on the detected orientation of the user 41 relative to thevehicle 40 or the loading crane 14. Control commands can further becarried out depending on the detected position of the part of the body42 of the user 41, in which case that can for example also include thegeneration of control commands by the detected position of the part ofthe body 42 of the user 41 (gesture control). Furthermore, controlcommands can be carried out depending on the detected visual field 43 ofthe user 41 relative to the loading crane 14. Thus, for example, theimplementation of control commands can also be prevented if it isassumed, by virtue of the detected visual field (or also the detectedposition) of the user 41, that the visual field or the user is notdirected towards the vehicle 40 or the loading crane 14 or a workingregion of the loading crane 14.
